be found again, we may also consider the possibility of a mutation 

 sufficiently fixed to reproduce its kind. 



? . Fore wing as in eltringliami, more thinly scaled, basal costal 

 stripe longer, a small spot in base of 3, and spot in 2 larger. Hind 

 wing with basal black and discal black spot as in the allied form, but 

 discal spot joined to the black area. The costa and a broad distal 

 margin are hyaline, thinly scaled with black as the fore w T mg. 



Underside of hind wing with separate large black spots and grey- 

 green basal scaling. A spot at the base of 7, one in cell produced 

 basad, one below the cell at base, a large discoidal patch lying mostly 

 outside the cell, a small spot in base of 3 joined to the previous patch, 

 larger spots in 2, lc and lb, separated by the veins. 



Length of fore wing : 20 mm.

6. Euphaedra christyi Shpe. barnsi subsp. nov. 



The discovery of this form induces us to regard christyi as a species 

 and not as an aberration of zaddachi Dew., as Aurivillius considered. 

 Typical zaddachi was obtained at the same place as barnsi. 



E. christyi is distinguished from zaddachi by the ochre-yellow area 

 of the hind wing, which is smaller than the red area in zaddachi, but 

 in the 2 is partly red. The inner margin is grey or black. The 

 hind wing below has the costal area red in the S , only in the ? with 

 extended red, and with this the pale areas of ground-colour are larger 

 than in ? zaddachi. There is a black discoidal spot, always absent 

 in zaddachi. 



$ . Upperside of fore wing with markings white or with a yellowish 

 tinge. Subapical band shorter and more curved than in the type form, 

 not reaching below vein 4. Cellspot absent. Median band shorter, 

 not produced to the base of cellule 2, and with a smaller spot behind 

 vein 2. Hind wing discal patch smaller than in the type form, and 

 reduced distally. 



Underside of fore wing with bands as above, and other markings 

 as in type form. Hind wing with red costal area, reaching vein 6 

 and with a large distal spot in cellule 6, and another below it in 5 

 (absent in one specimen). Five postdiscal black spots in 2 — 6, and a 

 spot in 7 more proximal. Submarginal spots as in type form.
